Oilfield Grade HPAM Polyacrylamide for EOR Mobility Control with 5-25million Molecular Weight in 25kg/bag
Oilfield Grade HPAM Polyacrylamide for EOR Mobility Control
Optimized polymer for viscosity enhancement, sweep improvement, and high-performance mobility control in enhanced oil recovery.
This Oilfield Grade HPAM (Partially Hydrolyzed Polyacrylamide) is formulated for EOR mobility control operations requiring stable viscosity, low degradation, and reliable injectivity. The polymer is designed to build strong water-phase viscosity at low concentrations, allowing injection water to sweep a larger portion of the reservoir while reducing channeling and water breakthrough.
Product Purpose
This HPAM grade enhances the mobility ratio between injected water and crude oil, enabling more effective displacement. The product dissolves efficiently in low-salinity water and maintains structural integrity under shear, making it highly suitable for polymer flooding and injection programs in oilfields.
Key Functional Advantages
- High molecular weight for strong viscosity building at low polymer usage.
- Excellent mobility control to improve conformance and sweep efficiency.
- Stable hydration with minimal shear degradation.
- Good compatibility with typical low-to-moderate salinity injection waters.
- High purity and low residual monomer for improved environmental and operator safety.
How It Works in Mobility Control
Mobility control relies on increasing the viscosity of the injected water to balance the mobility ratio between water and oil. When the injected fluid moves more uniformly through the porous reservoir, oil trapped in low-permeability zones can be effectively mobilized. This HPAM provides predictable rheological behavior that helps maintain injection stability over extended periods.
Recommended Operating Conditions
- Temperature range: Low-to-medium temperature reservoirs.
- Water quality: Compatible with fresh water and moderately saline injection water.
- Reservoir type: Best suited for sandstone and unconsolidated formations.
- Injection design: Supports continuous and slug polymer flooding programs.

Engineering Notes
Successful mobility control requires matching polymer grade to reservoir conditions, ensuring water compatibility, and optimizing injection strategy. This oilfield-grade HPAM provides a strong balance of viscosity performance, injectivity, and long-term solution stability for a wide range of EOR projects.
